Hmm, personally if I had a veil with that dress I would go for a long one so that it “flows” in the same way as the dress. Maybe waltz/ballet length? but i think a 20s style headband would also look amazing!

I would say a fingertip length or longer. Maybe a cathedral length veil. Definitely nothing with too much volume; I would say something with just one layer of fabric, and maybe some pretty detailing along the edge.
